Peripheral blood and haematopoiesis in bone marrow and liver tissue were investigated in Bufo bufo during the sexual cycle. A combined touch and imprinting tissue method were applied for the haematopoietic cell isolation. The liver is the primary site of erythropoiesis and partial lymphopoiesis. There was a positive correlation between body mass and liver mass, but it was not significant (P > ). The primary role of yellow bone marrow is the maturation of haematopoietic cells, while red bone marrow is responsible for the production of blood cells. |
